Improved lining for journal-boxes



UNITED STATES PATENT OFFICE.

P. S. DEVLAN, OF JERSEY CITY, NEW JERSEY.

IMPROVED LINING FOR JOURNAL-BOXES.

Specificationforming part of Letters Patent No. 59,564, dated November13, 1866.

To all whom it may concern: I

Be it known that I, P. S. DEVLAN, of Jersey City, in the State of NewJersey, have invented anew and useful Lining for Journal- Boxes andother Rubbing Surfaces; and I do hereby declare that the following is afull, clear, and exact description thereof.

My invention consists in the employment of pasteboard saturated withoil, and then subjected to pressure and inserted in suitable recesses injournal-boxes and other rubbing surfaces to reduce friction.

I have discovered that if the material generally known as pasteboard,whether made by pasting together several thicknesses of paper ordirectly of the thickness required, be saturated with any of thelubricating-oils, such as petroleum, and then subjected to pressure,

it can be used with great advantage to reduce the friction of metallicrubbing surfaces.

I take pasteboard made of considerable thickness, say from a quarter tohalf an inch, and cut it of suitable size to fit in the recesses ofjournal-boxes such as have been usually made to receive what is Wellknown as Babbitts metal. The pieces so cut I immerse in petroleum orother lubricating-oil until it becomes thoroughly saturated-that is,until the oil strikes through the pasteboard. If the oil be cold it willtake about half an hour; but it can be done in about five minutes if theoil be heated. The pasteboard so saturated is then to be subjected toheavy pressure, which pressure I prefer to apply at the time ofinsertion in the cavity of the box or other article to be lined.

The recess in the surface of the box or other article should be of lessdepth than the thickness of the saturated pasteboard after it has beencompressed, and in compressing the saturated pasteboard care should betaken to use a smooth compressing-surface.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is

Lining journal-boxes and other rubbing surfaces with pasteboardsaturated with lubricatin g-oil and then compressed, substantially asand for the purpose described.

P. S. DEVLAN.
